<pre>The code decodes to
1c: 51 push %rcx
1d: 48 8b 47 18 mov 0x18(%rdi),%rax
21: 48 8b 38 mov (%rax),%rdi
24: 48 8b 87 50 03 00 00 mov 0x350(%rdi),%rax
2b:* 48 8b 00 mov (%rax),%rax <-- trapping
instruction
2e: 48 85 c0 test %rax,%rax
31: 74 02 je 0x35
33: ff d0 callq *%rax
35: 31 c0 xor %eax,%eax
37: 5a pop %rdx
38: c3 retq
Which means that port->func is NULL. Still trying to work out exactly how that
happens.</pre>
